Freema Agyeman, ready to appear in the next season of Torchwood has spoken out about her appearance in Torchwood in a BBC Press release.

She says: "Martha has grown up a lot since Doctor Who. She's now a fully qualified doctor and a bit hardened by life experiences. When she finds out that Captain Jack needs her help, she joins Torchwood for a while. She continues to develop her knowledge of alien intelligence, but this time keeping her feet on the ground."

"And for me as an actress, it's a great new challenge to be able to broaden and expand Martha as she develops in other directions for this more adult series. The Torchwood team are fabulous to work with and have made me very welcome."
